CNC(computer numerical control) coordinate transformation library was developed, which could be integrated into CNC system as a coordinate transformation control module. The kinematics of 5-axis machine tool was analyzed, 12 types of 5-axis machine tool structure were listed, and the corresponding coordinate transformation algorithms were derived. 3 types of basic algorithms were obtained through mathematical transformation, and a 5-coordinate transformation library was developed based on the basic algorithms. The feasibility of 5-coordinate transformation library was verified by a 3D simulation system, and the library was integrated into CH-2010 open CNC system developed by Beijing University of Aeronautics and Astronautics.
